Title: Fuel quantity measuring apparatus for testing engine fuel injection equipment
IPC: G01F1/00
Filed: 1976-03-01
Abstract: 1519392 Testing fuel injection pumps and injectors LESLIE HARTRIDGE Ltd 24 Feb 1977 [1 March 1976] 8108/76 Headings F1A and F1B [ Also in Division G1] Apparatus for measuring the quantity of fuel delivered by a fuel injection pump (100), Fig. 1 (not shown), to injectors 10 comprises transparent vessels 33, 41 containing pistons 42, 43 movable in one direction by fuel from the injectors to provide a reading of the delivery and movable in the opposite direction by a liquid, e.g. fuel from a test bench, (Fig. 1). In the embodiment shown vessels 33, 41 are connectable via solenoid valves 62, 64, 66, 68 to an inlet 70 from a fuel pump and an outlet 72 to a fuel tank and via a slide valve 22, operable by solenoids 34 and 36, to the chambers 12 containing the injectors 10 or to the fuel tank. In use, the valve 64 is opened and the valve 62 closed or the valve 66 opened and the valve 68 closed to pressurize the large vessels 33 or the small vessels 41 and relieve the pressure in the small vessels or the large vessels. A control on the test bench is then operated to provide operation of an injection pump revolution counter for a predetermined number of turns during which the solenoid 34 is energized to move the valve 22 to the right so that fuel from the chambers 12 displaces the pistons 42 or 43 which are not subject to pump pressure. On completion of the predetermined number of turns the solenoid 34 is de-energized and the valve 22 is moved by the spring 38 to the position shown in which the chambers 12 are connected to return passages 26, 24 to the tank and inlet ducts 32 to the vessels are closed and the pistons 42 or 43 indicate the injector deliveries. To discharge the fuel below the pistons 42 or 43 the valve is moved to the left by energizing the solenoid 36 and the valve 64 closed and the valve 62 opened or the valve 66 closed and the valve 68 opened so that pump pressure acts on the pistons 42 or 43 and the displaced pistons are returned to their zero positions with the fuel flowing back to the tank via the ducts 31, 27, 29. The valves 62 to 68 may control the application and relief of air under pressure on liquid in the vessels above the pistons, Fig. 3 (not shown). In another embodiment, Fig. 4 (not shown), the chambers 12 are connected to the vessels 33, 41 and the return duct to the tank under the control of non-return valves (55  to 58) which open above predetermined pressure differences such that operation of the valves 62 to 68 controls the flow of fuel from the chambers 12 to the vessels and from the chambers or vessels back to the tank. The fuel above the pistons 42, 43 may be pressurized or relieved by connecting a chamber (53), Fig. 5 (not shown), containing fuel, to the vessels above the pistons by opening solenoid valves (63, 65) and by connecting the fuel chamber above the fuel level to a source of compressed air or to exhaust by a solenoid valve (67).

Patent GB-872474-A (GB)
Title: Rustproofing metals and products thereof
IPC: C23C16/06
Filed: 1958-03-17
Abstract: In a method of treating a metal (e.g. iron) which is susceptible to corrosion to render it corrosion resistant, the metal is heated and vibrated to remove occluded gases from its pores and interstices, the thus heated metal is subjected to a gaseous heat-decomposable metal compound at a temperature below the decomposition temperature of said compound to impregnate said pores and interstices with the compound, the metal component of said compound having a greater resistance to corrosion than the metal being treated, and the resultant gas-impregnated metal is heated to cause decomposition of the compound and deposition of the corrosion-resistant metal in said pores and interstices. The metal is preferably subjected to sub-atmospheric pressure while it is being heated and vibrated. Vibration may be effected mechanically or by using pulsating electromagnets.  The temperature of the base metal may be increased after deposition of the corrosion-resistant metal to accelerate diffusion of the latter.  Suitable corrosion-resistant metals are chromium, copper, nickel, titanium, zinc and zirconium.  They may be deposited from such compounds as carbonyls, nitrocyl carbonyls, carbonyl halides, hydrides, nitrides, nitroxyls, alkyls and halides. The compounds may be entrained in a carrier gas such as carbon dioxide, helium, nitrogen or hydrogen.

Abstract: 1,027,536. Inserting leaflets in cartons. BIVANS CORPORATION. March 3, 1964 [March 8, 1963], No. 8870/64. Heading B8C. [Also in Division B6] An apparatus for inserting leaflets into cartons or the like moving at uniform speed comprises a gapped support on which each leaflet is placed, a ram then thrusting the leaflet through the gap into a carton beneath. The apparatus may receive cartons from a machine for setting them up from the collapsed tubular form. Collapsed boxes 2 are set up at station S1, their bottom flaps tucked in and they are placed upright and introduced into the pockets of a conveyer. The conveyer pocket members 16, 17 are adjustable for different carton sizes by means including a sprocket 11. The conveyer runs beneath the gapped bridge or support 30, Fig. 2, at station S4, Fig. 1, which comprises two relatively adjustable plates 36, 37 on a carriage 102. The carriage is reciprocated so as to move with the cartons during its forward travel and it carries the ram 70 mounted for vertical sliding along a rod 50 secured to the carriage. Leaflets 31 are fed from a magazine 32 by a suction cup 12, Figs. 2, 10. The cup is carried on an arm 115 mounted on a lever 76 pivoted to a further lever 80, the lever 76 being connected by a link 82 at one end and to a fixed pivot 83. The lever 80 is oscillated by cam means and a bell crank 58, Figs. 10, 11, 15 and the arrangement is such that the cup is given a thrusting movement in the direction of the length of the leaflet stack, Fig. 10, to facilitate release of the lowermost leaflet from a stop 59. The cup is moved to the position of Fig. 11 to deposit the leaflet on the bridge. The ram 70 then descends to thrust it into the carton, folding it to U-form in the process. The bell crank 58 has a projection 92 which engages a vacuum release element 43, Fig. 15, when the leaflet is deposited. A feeler 103 is engaged by boxes on the conveyer to act on the element 43 through a lever 117 and universal drive 116. Should no box be present, the cup 12 is connected to atmosphere and no leaflet is fed. The cam controlling the ram is adjustable relative to the conveyer drive so that a leaflet may be placed in a selected portion of the container, e.g. a compartment. A closure flap printing device 54 (not detailed) operates on the cartons after filling at 28, Fig. 1.

Filed: 1939-03-21
Abstract: 528,248. Electric supply ; transformers ; discharge lamps. BRITISH THOMSON-HOUSTON CO., Ltd. March 21, 1939, No. 8979. Convention date, March 22, 1938. [Classes 38 (ii) and 38 (iv)] [Also in Group XL] A discharge lamp with two anodes 3, 4 have these connected to the ends of a transformer secondary 13, whose mid point is connected to the cathode 2 either directly or through windings 14 supplying heater current to the cathode ; across one half of the secondary is connected a condenser 28 in series with a resistance 35 and switch 29. When the main switch 16 is first closed, the cathode heater circuit becomes operative, but the resistance 35 prevents discharge across the lamp until the bimetallic strip 34 short-circuits the resistance ; the condenser 28 and secondary then form a resonant circuit capable of applying sufficient voltage between the cathode and anode 4 to break down the discharge gap and start the lamp. The circuit through condenser 28 is opened during normal running by the switch 29 its attached armature 31 being attracted at the air gap in the leg 18 of the transformer. This comprises two E-shaped cores 9, 10 separated by a gap, the central legs providing a return path for the unidirectional component of the flux. Magnetic shunts 11 are arranged in the core part carrying the primary winding 12. To improve the power factor a condenser 24 and series reactance 25 are connected across the secondary 13, the reactance 25 being wound on a E-core 26 separated by non- magnetic material from the core 10. The lamp may have a fluorescent coating.

Title: Mower
IPC: A01D34/47
Filed: 1962-03-08
Abstract: 977,086. Lawn mowers. SUNBEAM CORPORATION. March 8, 1962 [March 17, 1961], No. 8980/62. Heading A1F. In a power-operated lawn mower guided by a handle and supported on ground wheels, the handle is movable to varying positions to control means for connecting and disconnecting the cutting means in drive relationship with the power means and to control means for connecting and disconnecting the wheels in drive relationship with the power means. As described a lawn mower powered by an I.C. engine 17 comprises ground wheels 7 supported on plates 9 pivoted to the mower frame and biased rearwardly by spring 41, and a cutter reel the shaft 6 of which carries at each end a roller 11. A handle 25 is pivotally connected between the side plates 2 and plates 9, at least one limb of the handle carrying a cam roller 30 engaging in a slot 31 in the corresponding plate 9. An output shaft 45 extends from the engine 17 and is coupled with a shaft 46<SP>1</SP> which carries a pair of driving and driven collars 46, 47 respectively, the collar 47 being geared to the cutter reel shaft 6. A spring clutch 48 surrounds the collars 46, 47, the end 77 of the spring co-operating with a clutch actuating finger 78 integral with a member 80, the finger being disengaged from the spring in the clutch engaged position. When the engine is started the roller 30 lies in a concave surface 35 in the slot 31 in which position both the reel and the wheels are disengaged from the drive. Rearward movement of the handle to bring the roller 30 into surface 36 rotates the member 80 to engage the clutch and engage a drive to the reel. As the handle is moved further the plates 9 are freed to pivot rearwardly thereby bringing the ground wheels 7 into contact with the drive rollers 11. Further downward movement of the handle pivots the plates 9 forwardly against the spring 41 to disengage the wheels from the rollers 11, the cam roller 30 then being located in surface 38 in which position a drive is still engaged to the reel.
